site sides of the main frame. The hanger support G can be shifted by anysuitable means, such, for instance.I a cam lever g* adapted to be rockedby a shiftin key g5 and acting on a roller or port y suitably attachedto the support. The sgort or plate G is preferably stamped from stock ofsuitable thickness and as rearwardly bent pivot lugs g by which'it ispivoted to the supporting arms. gs indicates openings in the ends ofthe'plate G in which are secured supporting rods, not shown1 for thetype-rest. rrheplate G is preferirblygrooved on its rear side to receivethe heads of securing screws It for the type-har hangers H H H2 H3. Thegroove for the securing screws for the central hanv'ers is shown at h',Fig. 1, and the grooves or the screws of the remaining hangers areindicated by dotted lines in said figure. The plate is thus grooved toreduce its thickness, so that the whole series of oblong holes la,through which the securing screws for the hangers pass, may be punchedat one operation. The holes for two extra. outside hangers are shown ath3, Fig. 7, these hangers being omitted. The other holes are of similarshape.- The front face of the plate G is plain or flat. The grooves kfor the screw heads and the slots through which .the screws pass arelarge enough to permit e limited vertical movement of the screwstherein, sufficient for alining the type.

In the construction shown in Figs. 1.473, the hangers H H H2 an H3 havebodies or attaching portionswv there secured in 'upright position,paralgl witheach other, on the supporting plat-e G, and bearing endswhich nre bent at the' necessary inclinations taille body portions topermit theA typehsars to swing in radial planes and make the impressionsat e connnon point on the` platen. The bodies of all of the hangers areof uniform thickness sufiicient 'to pro vide the required space betweenthe typewbsrs when the hangers are secured face to face on the support`and by mnl-.Iii'ig' their 'nearing ends of appropriate lengths to locetethe hearings in :in nrc7 as shown. the required spaces between thehearing ends are secured, such spaces increasing in width from thecenter toward the ends of the se ries. This increasing?l space isrequired to accommodate the increasing,r o'i'set or inclination given tothe heads of the typehars to enable them to nest properly in thetype-bar basket. The hangers may 'be formed from stock which is rolledin two dilerent thicknesses, suitable for the body and nearing portionsof the hangers, or the bearing ends may be reduced in thickness byswaging or machining. The hangers ere arranged in a central group andtwo side groups at each end of the central group, and are clampedtogether by screws z' e" i2 ie as presently explained. The hangers aremade in pairs,.or rights and lefts, and with bodies of two' difieren-tforms., as shown in Figs. 5 .and S. The hangers H hnvescrew threadedholes il (see Fig. (i) -in their bodies; the hangers H2 have similarthread ed holes at their lower ends, and the end hangers il? of theseveral groups against which the heads of the, clamping screws bear,have smooth holes slightly. smaller than the screw heads through whichthe screws pass. The remaining hangers H all have two open-ended slotslld, as shown in Fig. 5, for the passage of the ,clamping screws. Theclamping screws are of four dili'erent lengths. The screws z' and i' extend through the hangers of the two side groups at each end of theseries and have threaded ends screwed into the threadedl holes in thehangers H. rhe screw i2 passes through the center and. adjh'cent sidegroups and has a threaded end Ascrewed into the threaded hole in thehanger H2 of' one side group, and the other screw z" passes through thehangers of the central group and is simi l'sirly screwed into the hangerH2 et the end of this group. The securing screws k are screwed intoholes in the rear edges of the hangersthe holes being staggered to makeroom for the screw heads, as indicated by the dotted lines in Fig. 7.

In assembling the hangers, after the typebars here been pivotallysecured thereto and the operating links connected to the typehars, thehan ers are secured loosely on the supporting p ate G by the screws ll,after which the plate G is pivotally connected to its supporting armsand the operating links connected to the upper ends of the actuatinglevers. The clamping screws --c'a are not screwed in tightly until afterthe type-bars are elined, but they are screwed in far enough to createsullicient friction between the hangers to hold themegdinst accidentalmoiyement .while being alined. As fast ns the several bars are alinedthe hangers ther lor :ire locked to theI plate G by the screws if., andwhen all of the type-bars have been properly elined' the severalclamping screws -za are screwed in with suflicient force to rigidlychimp the whole series of hangers together thus makin a more rigid andreliable connection of t e hangers to the support tha/n is possible withhangers independently secured within the same space. Any one of thehangers H having the open slots een be detached whenever this maybeneeessary, by first removing securing screw la und loosening the twoclamping screws which pass through that hanger dis- :i-.finnecting itslink from the auxiliary lever and pulling the hanger straight outwardlyto the front. In the case of the hangers -H .and H2 having the threadedholes for the clamping screws, it is necessary te remove misst-ss theclamping screws also. ln any any desired han-gers can be letacnez'l andreplaced without. disturbing the others. A convenient way to assemblethe hangers is to first loosely clamp together by the screws il the t,rs of the central group, than loosely clamp together the nine hangers ateach. of the two side Agroups by tue tue short screws i z". The iyegroups are then placed together and loosely clamped by the screw i2.,This is allv done before securing the grouped hangers on the supportingplate G. The hangers Construct-edA and arranged in this manner may costslightly more t-o-produce thansome'forms of hangers now in useA` whichare arranged inradial lineson their support5 but the support (l is lessexpensive than one made for radially :arranged hang ers, sotliat lthetotal cost is about the same. But an 'absolutely Arigid' support for thetype-bars is produced and the hf-ingers cannot become loose by reason ofside s lus causedl byv CollisionsA between .the typwmrs. and so muchtime' is saved in alining the type that the described construction-is inreality much less costly than other ronstructions of comparativefvaluelvTl e :great advantage gained in alining the type will he readilyappreciated; when it is' understood that any 'of the type" may-be raisedor lowered vertically at 'right angles. to the print inglinewi'thoiitua'ffecting the lateral position of the type at-theprinting point, oy simply adjust-ing'the'hangers" vertically up or down.`The wholeseries'of type-bars can be properly alined with the 'same easeand speed thatis ordinarily required to aline the central bar yinjrnaelinesA ha'ing )radial hangers. Thusnot only is there an importantsaving' in t'inie'of the' most expensive labor required vin the'manufacture of 'type writers, but the Work canbe performed .with laborof less skill and consei-piently more economically.v 'y s Ball bearingsof the usual forms are not suitable for vpivoting thel type-liars to thehangers, since the hangers arranged in parallel planes within the smallspace 'shown do not afford sufficient room.A Therefore, hayingespecial-reference 'to the described coustruction of the hangers, thebearings are preferably constructed :rs follows: The hearing'emlof eachhangerismaehined to form a low cone frustum Kpn one'side thereof and `isrovided with a relatively large ceuA tral ho e c.

The inner end of earhtypeliar is made with fan internal .annulas' ball race or groove and a.circular 'row ot' halls .t5 is confined-between this race and the balls,or until the adjustable .cone acting,-

with the fixed cone has forced the halls into the race inthe type-bar soas to prey-ent. looseness. Then the parts aie locked by srrewing in thelocking-screw 1* with ftonsideralile force. Y. Y

Should the bearing be-sti it only nee-- -ry to unloelr-itandscrew in thad justing plate It? slightly: and again los-lr .itA as before. As theshank oyt'ne adjustable eene is held from turning inthe cone it isevident that theadjust-ing vplate is held against turning in its seatwhen the locking screw is screwed in tightly. Y The adjust'- ing plate1? is made with slots cris. otlrexy wise formed Vfor the enragenient ofa tool for turning it., and it is'msopreerably split as shown` andslightly- Vexpanded*so thstritls to .be connu-esseri somewhat tovsere'fvit into place.

Preferably, however, the cone extension is lfittedloosely in the fixed cone. as shown. and the balls are relied upon toforce theadjustable cone into proper roncentric relation to the fixedcone when adjusting the bearing. The balls naturally do this if alittl.. Care is used in making the adjustment, and, vwhen locked, theadjustable cone will retain its position. ln either case the troublecaused by a loose or eccentric locking screw is overcome, as the onlyfunetion'of the screw le* is to rigidly lock the adjustable cone to theadjustin '"plate.

'Il machining the hangers to form the fixed bearing cones K. a smallflange or dust guard k' is preferably left on the upper end of the.hanger which overhangs the space between the hanger and the vtype-bar atthe upper rear portion of the bearing. The universal bar hereinafterdescribed extends over.

these guards on the several hangers, so that the guards prevent any dustthat may fall behind the universal bar from entering the bearings. l

L represents a curved universal bar which is substantially parallel withthe are of the type-bar bearings and is supported over the bea rings inposition to be struck by the typebars as they approach the platen.preferably in the. following manner: M represents a bar which is'secured. for instance, by screws m to lugs m. ou the upper central partof the plate (l and is provided at its ends with cross arms m?. ln thefront and rear ends of these. arms, parallel rock shafts 'mil m* arejournaled which are provided with rigid dependingI arms m. 'lheuniversal bar has fixed thereto rearwardly extending; arms m which arepivoted to the said depending rock arms 'mf". The universal bar is thushung so that it is adapted to be n'ioved rearwardly when strurlc by anyone of the type bars. .X suitable spring,r m7 arts to restore theuniversal bar to its forward or normal position. 'lhe spring: shown isconnected at opposite ends to an arm m, on the rock shaft m3 aud to anarin lm" on one leg ol' the renter guide. for the type-bars hereinafterdescribed The universal bar is connected te: the carriage escapement foraetuating it. preferably as follows: N represents a nearly horirontallink pivoted at its front end t0 the rot-k arm me and at its rear end tothe depending arm of a bell crank lever u which has a rearwardlyextending arm ronnerted by a rod n' to the rontrollinv lever Il of theCarriage esen pement. The bell crank lever n, is pivoted on a bracket nsecured to the supporting bridge for the carriage track. As the carriageescapement is mounted on .a fixed part of the machine while theuniversal bar is mounted on the shifting supporting plate G, the link Nis pivoted to the bell crank n m a plane midway between the normal andshifted positions of the pivot which connects the link-to the arm nr. sothat the action of the escapement will be the. same in both positions ofthe supporting plate G. By these connections the escapexnent wheel isreleased every time the universal bar is moved rearwardly by a type-bar,and the spring m acts to restore the eseapement lever as wellv as theuniversal har to the normal posit-ion.

0 represents the vibrating ribbon guide or vibrator, which may beconstructed and mounted in any suitable Way. The vibrator shown has earso by which itis slidabl retained on a stationary renter `duide for thetvpe-bars and it is pivoted at its lower end to the front end of a.vibrator lever Q. The center guide shown has downwardly and rearwardlyextending: legs p rigidly secured to the bar W. preferably by theseturing;r screws fortliis bar. The center guide slides up or down infront of the vibrator when the type-bars are shifted to differentprinting: relations to the platen and always retains a fixedpositionrelativix to the typebars. The vibrator 0 also actuated b v theuniversal bar through mechanism,which. as shown in Figs. 19, isinstructed as follows: 1' and r'- represent two arms of diferent lengthswhich project 'from a hub R loosely sleeved on the central part of therock Shaft m. A nut ''2 screwed on the shaft 'ms and bearing against thehub of the arms r r' retains a tapered stud 'r3 on the rock arm m8 in ahole in the arm r. whereby the arms r, 'r' are locked to the rock shaftmi so that they will be rocked when the 'aniV` versal bar is actuated.vWhen it is desired to silence the vibrator, the nut r2 is am screwed',when a spring?A between the arms m and r will disengage the. latter armfrom the stud 1". to the rock shaft by again screwing; np the nut r2,
